Abstract

This paper presents the language identification (LID) system developed in Speech@FIT group at Brno University of Technology (BUT) for  NIST 2005 Language Recognition Evaluation.

Annotation

This paper presents the language identification (LID) system developed in Speech@FIT group at Brno University of Technology (BUT) for  NIST 2005 Language Recognition Evaluation. The  system consists of two parts: phonotactic and acoustic.  Phonotactic system is based on hybrid phoneme recognizers trained on SpeechDat-E
database. Phoneme lattices are used to train and test phonotactic language models. Further improvement is obtained by using anti-models. Acoustic system is based on GMM modeling trained  under Maximum Mutual Information framework. We describe both parts and provide a discussion of performance on LRE 2005 recognition task.
